Abstract
An apparatus, system and process is provided for communicating safety-related data, over an open system, from a sender to a receiver. Safety-related components, including function blocks, flexible function blocks, resource blocks and transducer blocks, as well as, safety-related objects are provided. Also, an extended safety-related protocol provides for authenticating communications between safety-related components over an existing black channel, such as one using a fieldbus Architecture.
Claims1
An apparatus for operating in a block-oriented safety related open control system comprising:
- a memory, which includes at least one safety related component;
- a processor, operably connected to the memory, wherein the processor executes the safety related component based on a system schedule;
- and
- a medium attachment unit, which translates input messages and output messages between the processor and a transmission medium using an extended safety-related protocol.
